Thanks! Reading up now. I've been using several exploits for a while now, so I'm interested in seeing what this can do!
(EDIT: Now that I'm using it, I see it doesn't allow backups to load without a swap, which is fine because I already have a flip-top lid on my v7. I can't get CDloader/DVDloader to work with it, but SwapMagic 3.8 ELF and HDadvance work fine. The only benefit so far is not having to pop in a PSX disc to boot the memcard, but that wasn't a big deal anyway.
I could take this or leave it.)
